Applicability of Atmospheric Pressure Plasma Jet (APPJ) Discharge for the Reduction in Graphene Oxide Films and Synthesis of Carbon Nanomaterials

Atmospheric pressure plasma jets (APPJ) are widely used in industry for surface cleaning and chemical modification. In the recent past, they have gained more scientific attention especially processing of carbon nanomaterials. this work, a novel power generation technique was applied to realize stable discharge N2 (10 vol.% H2) forming gas ambient conditions. This APPJ reduce solution-processed graphene oxide (GO) thin films result compared with an established optimized reduction process low–pressure capacitively coupled (CCP) radiofrequency (RF) hydrogen (H2) plasma. The reduced GO (rGO) were investigated by Raman spectroscopy X-ray photoelectron (XPS). Effective deoxygenation observed after quick 2 s treatment AAPJ. Further at longer exposure times found proceed expense GO–structure integrity. By adding acetylene into same APPJ, nanomaterials on various substrates synthesized. materials characterized spectroscopy, scanning electron microscopy (SEM), energy-dispersive (EDX) analyses. Fullerene-like particles graphitic short nanotubes detected Si Ag surfaces, respectively. We demonstrate that tool has obvious potential versatile
